To top Ripple and get to #3 ANC would have to be worth $116 each, by my calcs. If Zerocoin is successful it will be a monumental step for cryptocurrency. Considering the low supply side sell pressure for a tightly held, low supply coin, and the demand for ANC with ZC, I think it could get there but it would be a phenomenal thing!
Ripple is not a crypto currency, its debt based fake crypto money/coins.
